As part of our ongoing series of web seminars, CEO Jeffery Payne and Principal Consultant Rich Mills held a discussion about containers and the various ways you can leverage them to improve your software development, test, and deployment process.
During the conversation, they two discussed how modern organizations use containers in the development lifecycle, how containers support a ‘shift left’ philosophy for software testing and application security, and how containers can be used to continuously deliver applications from development through testing to production. Additionally, the two took questions from the audience about how containers interact with data, using different data sources by environment in testing, and where to get started with containers.
Check out some of the highlights below, or view the presentation and slide deck here.
…so I will say for anybody who hasn’t started using containers or doing stuff with containers, using them first is a great way to get kind of introduced to what it means to run Docker containers. And the best way that I can think of to do that is to use Docker containers, or containerization in general, in your DevOps build chain.
For example, let’s say you’re running a Jenkins server. In the classic world your development engineering teams will be running this Jenkins build server. It’s got a master that dictates things and then it’s got a bunch of agents that do work and those typically are a bunch of the ends. Well by going to something like Docker, suddenly now you’re able to just bundle these tools together…
…It also makes it much easier to scale. If I start building more and more services, more and more applications, I can scale these things out very easily using Docker…
…this actually encourages behaviors that let me build in and bundle my functional execution tests along with my source code, so that as I’m delivering updates to my source code, I deliver updates to my tests, as well. They kind of travel along together through your delivery pipeline. Anytime I fire up a container, I fire up the test right next to it, and I can execute it…
…There’s definitely a learning curve associated with learning how to manage Docker and configure Docker containers. The easiest way to do that is for your developers, or maybe your DevOps tooling team, whoever manages your build servers to use prepackaged containers everywhere…to learn how to use the build tools associated with making containers first before using containers. That really allows you to kind of dip your toe in the water slowly without over committing to it…
